COMP Cams Camshaft LS1 XR265HR-15

If you're looking to get more out of your GM LS engine, a camshaft upgrade can make a significant difference. This COMP Cams XR265HR-15 camshaft is designed for a wide variety of LS-based engines, including those found in popular vehicles like the Chevrolet Camaro, Corvette, and Silverado trucks. It's a hydraulic roller camshaft that aims to improve performance across a broad RPM range while maintaining good street manners.

This particular grind, the XR265HR-15, features a 212 degrees of intake duration and 218 degrees of exhaust duration with a 115-degree lobe separation angle. This setup is known for providing a noticeable boost in throttle response and overall power, especially in the mid-range, without becoming too aggressive for daily driving. It's a well-built component that can transform the feel of your engine, making it more responsive when you need it. Keep in mind that camshaft upgrades often require supporting modifications, such as upgraded valve springs, to perform optimally and safely.

This camshaft is a solid option for LS swaps or for owners looking to enhance their existing LS-powered vehicle. It's engineered to work with a range of LS displacements from 4.8L up to 7.0L, though specific cylinder head designs can influence the final outcome. Because it's a hydraulic roller design, it offers the benefits of reduced friction and wear compared to older flat-tappet designs, contributing to its longevity and performance.
